Function Generator Circuit using IC L8038 is chip makes sine, square and sawtooth wave; it changes frequency using outside capacitor and resistor from 0.001Hz to 300KHz. We can change and sweep frequency with outside voltage, as it gives strong and clean output and make all 3 waves of same time. Thus, circuit need few extra […]

Frequency Divider Circuit
To begin with, a Frequency Divider Circuit take signal with high frequency and give signal with lower frequency, also it changes the signal in way to reduce frequency. Two common ICs used for this: IC 4017 Decade Counter: IC 555 Timer: Circuit Working: Parts List: Components Values Quantity Resistors (All resistors are 1/4 watt unless […]
Simple White Noise Generator Circuit
The Simple White Noise Generator Circuit is a DIY project that produces sound like radio hiss or static; so we use this circuit for sound effects, privacy noise, and testing audio equipment.” Noise come from electronic parts, so we can use resistor or reverse transistor for noise, also capacitor remove too high or too low […]
TV Remote Signal Jammer Circuit
The 555 IC is used in this TV Remote Signal Jammer Circuit because it generates fake IR signals similar to a remote, as a result, the TV becomes confused. Furthermore, TV can not get the real remote signal, so we can watch the show without anyone changing the channel. Also, parts used to complete this […]
Analog to Digital Converter Circuit using IC 555
The easy way to change sensor voltage (analog) to digital (1 and 0) is by using Analog to Digital Converter Circuit using IC 555; as this method is cheap and easy for good learning. Here, IC 555 chip can make simple ADC with low cost and also in this circuit 555 IC work like ON/OFF […]
How to Design Crystal Oscillator Circuit
To Design Crystal Oscillator Circuit we need know some basic things; first use crystal to make steady frequency and then choose right crystal and connect with other parts like resistor and capacitor. After that, be sure circuit give right signal for our device. Therefore, these easy steps help us build good working circuit. Circuit Working: […]
